Under relaxation with PISO ?

hi all,
I've had a look on the PISO and SIMPLE algorithm and, as far as I understand the SIMPLE algorithm expects under-relaxation factors while PISO doesn't. So here are my questions: Do I have to set under-relaxation factors in SIMPLE each time I use it ? or can I omit them without risking divergence ? Moreover, can I use them with PISO even though it doesn't expect any ? Thank you for lightening my mind! |
